Popular animated characters Billy & Mandy (from the TV show THE GRIM ADVENTURES OF BILLY & MANDY) enjoy a feature-length series of fun and frolics in this, their first movie. The story finds Billy and Mandy (and their sidekicks, Grim and Irwin) chasing the Boogey Man across the high seas. The Boogey Man is determined to lay his hands on an ancient artifact called Horror's Hand, which has the power to turn him into a very scary creature. Plenty of swashbuckling action ensues as the race gathers pace, and the pirate theme is sure to appeal to PIRATES OF THE CARIBBEAN fans.
